Empty cdroms are not going to connect, avoid waiting for the backend to
switch to state 4, which is never going to happen, and return
error instead from XenPvBlockFrontInitialization(). Detect an
empty cdrom by looking at the "params" node on xenstore, which is set to
"" or "aio:" for empty drives by libxl.

Changes in v2:
- better commit message
- return EFI_DEVICE_ERROR instead of EFI_NO_MEDIA
- check the return status of XenBusIo->XsBackendRead

I test-built this for X64 and Ia32, and then committed it to SVN as rev
18651.
Thanks!

Thanks to both.
I tested it with a git cherry-pick on my tested build of some days ago.
With ide disks it boots correctly and xl cd-insert and xl cd-eject are
working.
With pvdisk don't start, but this time instead freeze on "tianocore
logo" but freeze with black screen after initial windows boot.
I retried for take full logs as possibile but it booted correctly and
with xl cd-insert and xl cd-eject was working.
I retried other 2 reboot without problem but at the third windows freeze
after arrived to login screen.
I suppose that this patch is ok and the problem is another but I not
understand exactly what.
In attachment full qemu log and xl dmesg about the latest test where
windows freezed at login screen, rdp and xl shutdown was not working,
its qemu process was still active and with near 100% cpu usage.
If you need more informations/tests tell me and I'll post them.
Thanks for any reply and sorry for my bad english.

Yes, that's likely a completely different bug. Does it only happen using
OVMF as guest firmare? I am saying this because it looks like the guest

In any case it might be good to repost it as a separate bug report to xen-devel.
Thanks again for testing,
